RAR archive of 7.14 MB with the name ECHIPS joyar56-5-g13 v10r2. The tokens do not identify a laptop brand, board number or chip clearly, so treat the contents as unconfirmed until the archive is opened; v10r2 looks like a version marker. Archives of this kind in repair collections usually hold firmware images or programmer software, and any image must match the target chip before use. Check chip markings and capacity, verify the dump against the board, and always save the original flash contents with a programmer before writing anything.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosdumpcomputer. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
